Just got our 2017 Forester MBS 2401R. I've seen other posts about tire pressure, but no definitive answer. The tags on the door frame say 61lbs, the tires have 80 lbs on them. Which one is it? We have taken 1 short trip so far and weighed in about 50 lbs overweight. Anything we should be worried about?

I have 2016 Forester MBS 2401R. I put 65 psi in all tires and work great with tire safeguard system that factory set at 65 psi cold setting. Also Les Schwab seems to know that was air pressure to set at too. Yes the sticker at the door said 61 psi. I bought tires monitoring system because I was so concerned. So far after 5 trips 65 seems the set point for my 2401R.

Tire safeguard system set at 57 psi low and 85 psi high. At 60 mile/hour tires pressure went up to between 79 and 80 psi in hot day. I think if they are good in 57 and 85 but considered when they hot and moving.

With a motorhome unlike a travel trailer the tire pressure should be varied depending on the weight of the vehicle. 80 psi is the max pressure for the tire to carry max load. there should be a loading chart that gives the tire pressure depending on Gross weight on each axle.

It would not be unusual for tires to exceed 80 PSI if they were could inflated to near that number. Filling to 80 when cold and the expected rise in pressure when operating is all taken into account in design limits.

The RV manufacturer and tire manufacturer work out the inflation requirement based on the tire and the vehicle weight, and that is posted on the door panel. There should never be so much or really any controversy about this. Follow the RV's GVWR of course and if following that then follow the tire inflation posted on the door panel. "Max pressure" stamped on the tire is just that, a maximum, never a guide. All pressures are to cold inflation. Don't change them during the day after driving; the pressures will naturally be higher then.
